Who uses the AD 310 and for what
The Bernardo AD 310 is the benchmark combination planer for joinery and artisan workshops requiring planing up to 310 mm in continuous cycles. Its 295 kg structural weight distinguishes it from entry-level planers weighing 150-180 kg: the mass provides stability during passes on hardwoods like oak and ash, where lighter machines exhibit micro-vibrations visible on the finished surface. The non-deformable cast iron tables offer flatness over time, even with temperature variations in the workshop, a critical factor for window and door manufacturers and furniture makers working to tight tolerances.
Its place in the Bernardo range
In the Bernardo range of combination planers, the AD 310 occupies the entry-professional segment: above hobby planers with 2.2 kW motors and 150 kg structures, and below the ADM 300 models which add a helical feed roller and sound-absorbing lips for extended industrial cycles. The choice between AD 310 and ADM 300 depends on the intensity of use: for shifts up to 6 hours, the AD 310 is sufficient; beyond 6 continuous daily hours, the ADM 300 reduces the risk of thermal stops. Switching from jointer to thicknesser is managed by the double tilting of the rear tables, an operation that takes less than 60 seconds in the workshop.

Who is the Bernardo AD 310 for
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Suitable |
Oversized machine for occasional use: the 400V three-phase motor requires a dedicated electrical system. Consider a single-phase version if available. |
| Small joinery / artisan (1-5 employees) |
Recommended |
310 mm covers 95% of work on standard boards and panels. The 295 kg provides stability without special foundation. 400V three-phase is the standard in Italian joinery workshops. |
| Continuous / industrial production |
Suitable |
For shifts exceeding 6 hours daily, consider the ADM 300 with helical roller and sound-absorbing lips, designed for more intensive cycles without thermal stops. |
Not suitable for: workshops with only 230V single-phase power without the possibility of a three-phase system; processing panels wider than 310 mm (consider the AD 410); workshops requiring variable selectable feed (the AD 310 has a fixed feed of 6 m/min).

Frequently asked questions
Does the AD 310 work with 230V single-phase power?
No. The Bernardo AD 310 – 400V requires 400V three-phase power. For workshops with only a single-phase socket, the ADM 260 – 230V version or other models in the Bernardo range in a single-phase configuration are available. The 400V three-phase power supply is standard in Italian joinery and artisan workshops equipped with an industrial meter. The 3.0 kW three-phase motor offers smoother starting torque compared to single-phase motors of similar power, reducing absorption peaks at start-up. Before purchasing, verify with your electrician the presence of a dedicated three-phase line with adequate protection (typically 16A).
What is the maximum working width for thicknessing?
The effective thicknessing width is 310 mm, with adjustable passage height from 5 to 225 mm. The maximum depth of cut per pass is 5 mm, with 2-3 mm recommended for precision finishing on hardwoods. The 310 mm covers boards, strips, and panels of the most common sizes in Italian joinery: standard interior doors, kitchen countertops, glued laminated timber beams. For panels wider than 310 mm, it is necessary to consider the AD 410 (400 mm) or work in multiple passes by splitting the panel.
How often should HSS knives be replaced?
In continuous professional use (4-6 hours/day), the 4 HSS knives require sharpening every 2-4 weeks on softwoods, every 1-2 weeks on hardwoods. Complete replacement depends on the number of sharpening cycles (typically 5-8 cycles before discarding). The HSS knives for the AD 310 are available as original Bernardo spare parts from Krollit stock with 3-5 business day shipping. The included setting gauge provides precise knife positioning after each replacement, a critical element to avoid surface steps on the planed board.
What dust extractor is needed for the AD 310?
The dust extraction port is Ø 100 mm. A dust extractor with a minimum flow rate of 600-800 m³/h is needed to effectively capture chips in thicknessing mode. Bernardo DC 300 and DC 600 are the manufacturer's recommended solutions. The chip collection hood is foldable and integrated into the machine: during jointing, it can be folded away to avoid obstructing the operator. For enclosed spaces without a fixed dust extraction system, the mobile Bernardo DC 300 (400V) is the most common solution chosen by Krollit customers.
How much space is needed to install the AD 310 in the workshop?
The machine dimensions are 1,610 × 1,045 × 1,100 mm. For workpiece handling, at least 2.5 m of clear space is needed in front of and behind the machine, for a total operating area of approximately 6.5 × 1.5 m. The alignment tables open at the back of the machine: this feature allows for wall placement on the front side, optimizing space usage in narrow workshops. The 295 kg weight does not require a special foundation. Check access to the workshop (minimum recommended door width 1.2 m).
